Dormer Pramet A976 11.50 mm HSS-E HIGH PERF MULT-APP STRAIGHT SHANK EXTRA LONG SERIES (1) DRILL DIN 1869 / 1

Meet the Dormer Pramet A976 11.50 mm HSS‑E High Performance Multi‑Application Straight Shank Extra Long Series Drill (DIN 1869). This long‑reach bit is purpose‑built for deep‑hole work, delivering precise diameters, dependable performance, and a clean finish across a range of metals.

• 130° point for self‑centering – reduces the initial push force and guides the drill to accuracy, helping you start holes where you intend without wandering.
• Bright finish to minimize chip welding – the glossy surface helps prevent material from sticking to the cutting edge, promoting smoother cuts and easier deburring.
• Parabolic flute design for deep drilling – optimized chip evacuation and minimized cutting resistance, enabling extra deep holes in a single pass and reducing the need for multiple migrations.
• Premium HSS‑E (high‑speed steel with enhanced alloy) – versatile across common engineering materials, including steel, aluminum, and stainless steel, while maintaining edge retention under demanding workloads.
• Extra long length series – engineered for extended reach in tight pockets, long through holes, engine blocks, frame members, and other deep cavities where standard drills can’t reach.
• Straight shank DIN 1869 compatibility – reliable, rigid clamping in a wide range of chucks and collets, ensuring consistent runout and hole quality.

Typical use scenarios include automotive fabrication, aerospace component manufacturing, long‑reach repair work, and maintenance where deep, accurate holes are essential. The A976 drill stands out from standard bits by combining a precision‑first point geometry with a parabolic flute that handles aggressive chips without sacrificing finish or control. When you need to bore deep holes in steel, aluminum, or stainless steel with fewer passes and dependable straightness, this drill delivers.

Practical tips for optimal results:

• Use appropriate coolant or cutting fluid to extend edge life, especially on stainless steels.
• Start at a light feed, then increase gradually to maintain straight entry and prevent chatter.
• Ensure secure workholding and proper centering to maximize the benefits of the 130° point and long reach.
• Inspect the parabolic flute integration for smooth chip evacuation in deep holes; stop and clear chips if resistance increases.
